FATSC - SD and USB Coprocessor

15.10.2020 12:00

We are currently working on a new coprocessor to simply connect USB memory devices and SD cards to a microcontroller. The processor is compatible with the ALFAT SoC from GHI (ALF2X-SC-512).


  • USB-Host Mass-Storage Ports (MSD/MSC full-speed)
  • SD-Card interface (4-bit)
  • FAT/FAT32 file system with long file names (LFN) based on FatFs
  • Real-Time-Clock (RTC) with backup battery
  • Based on a ST STM32F205 ARM Cortex-M3 microcontroller
  • ALFAT SoC compatible pinout and commands (replacement for GHI ALF2X-SC-512)
